Find first 4 terms that are different from 0 for differential equation decomposition in Taylor series

[a157]

y'=2cos(x)-xy^2
y(0)=1
y'(0)=1
y''(0)=0
y''= -2sinx - 2xyy'

I can't calculate other derivatives

y''= -2sinx - 2xyy' ........................This is incorrect

Try again - carefully - step by step
